[0001] This utility model relates to the field of powder forming technology, specifically a powder side-pressure forming machine with a powder quantitative feeding structure. Background Technology

[0002] With the continuous development of industries such as powder metallurgy and ceramics, the demand for powder side-press forming machines is increasing. These industries need to produce powder products of various shapes and sizes, such as tungsten, molybdenum, diamond, graphite, ceramics, and powder metallurgy products. Traditional powder forming machines that press vertically cannot meet the processing requirements of products with special shapes such as holes or steps in the horizontal direction. Powder side-press forming machines can solve this problem and are therefore widely used.

[0003] Traditional powder feeding methods often fail to achieve precise quantitative control, resulting in unstable powder filling during powder side pressing molding. This affects the consistency of the molded product quality, such as uneven density and large dimensional deviations, which severely restricts the improvement of product quality and production efficiency. Moreover, the lack of an effective powder quantitative feeding structure also leads to powder waste and increases production costs.

[0004] Therefore, this utility model provides a powder side-press molding machine with a powder quantitative feeding structure to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a powder side-pressure molding machine with a powder metering feeding structure, such as... Figure 1-6As shown, the powder side-press molding machine with a powder quantitative feeding structure includes a base 1, a slide table 2 fixedly installed at the right end of the base 1, a fixed outer mold 3 fixedly installed at the upper end of the slide table 2, a lateral main pressure cylinder 5 installed at the rear end of the slide table 2, a rear forming mold 6 installed at the telescopic end of the lateral main pressure cylinder 5, a counteracting auxiliary pressure cylinder 7 installed at the front end of the slide table 2, a front forming mold 8 installed at the telescopic end of the counteracting auxiliary pressure cylinder 7, an electric telescopic rod 9 installed at the rear side of the fixed outer mold 3, and a demolding ejection assembly 10 installed at the telescopic end of the electric telescopic rod 9. The rear forming mold 6, the front forming mold 8 and the demolding ejection assembly 10 are arranged in parallel front to rear. A quantitative feeding assembly is provided at the upper end of the fixed outer mold 3.

[0019] The powder is quantitatively fed into the fixed outer mold 3 by the quantitative feeding component. Then, through the coordinated action of the lateral main pressure cylinder 5 and the opposing auxiliary pressure cylinder 7, the lateral main pressure cylinder 5 pushes the rear forming mold 6 forward, while the opposing auxiliary pressure cylinder 7 pushes the front forming mold 8 to maintain stability, ensuring that the forces at both ends of the cavity are balanced. The powder in the fixed outer mold 3 is laterally extruded and formed, so that the powder is subjected to uniform pressure in the horizontal direction, thereby forming a powder product of the required shape and size. During the forming process, the electric telescopic rod 9 can adjust the position of the demolding ejection component 10 as needed. After the forming is completed, the electric telescopic rod 9 pushes the demolding ejection component 10 forward to eject the formed product from the fixed outer mold 3.

[0020] The quantitative feeding assembly includes a powder storage bin 4, which is fixedly installed on the upper end of the fixed outer mold 3. A first drive motor 11 is installed on the lower side of the powder storage bin 4. A discharge port 12 is provided on the lower side of the powder storage bin 4. A conveying pipe 13 is installed at the lower end of the discharge port 12. The conveying pipe 13 is fixedly connected to the first drive motor 11. A quantitative feeding auger 14 is rotatably installed inside the conveying pipe 13. The quantitative feeding auger 14 is fixedly connected to the output shaft of the first drive motor 11.

[0021] When the equipment is running, the powder stored in the powder storage bin 4 enters the conveying pipe 13 through the discharge port 12. After the first drive motor 11 starts, it drives the quantitative feeding auger 14 to rotate. The spiral blades of the quantitative feeding auger 14 convey the powder evenly according to the set pitch and speed, so as to achieve precise quantitative feeding and avoid powder blockage or uneven feeding.

[0022] A material discharge buffer pipe 15 is fixedly installed at the lower end of the conveying pipe 13, and the lower opening of the material discharge buffer pipe 15 is flush with the upper side of the fixed outer mold 3.

[0023] The material feeding buffer tube 15 is made of flexible material and has a spiral flow guiding structure inside. When the powder enters the material feeding buffer tube 15 from the conveying tube 13, the spiral flow guiding structure can guide the powder to fall slowly in a spiral shape, further reducing the falling speed of the powder. At the same time, it can make the powder spread evenly above the fixed outer mold 3, improving the uniformity of powder filling.

[0024] A feeding rack 16 is fixedly installed on the left end of the base 1. A cross frame 17 is installed on the upper end of the feeding rack 16. A second drive motor 18 is fixedly installed on the left end of the cross frame 17. A first screw 19 is installed on the output shaft of the second drive motor 18. A sliding frame 20 is threadedly connected to the first screw 19. The sliding frame 20 is slidably connected to the cross frame 17. A vertical frame 21 is fixedly installed on the right end of the sliding frame 20. A third drive motor 22 is installed on the upper end of the vertical frame 21. A second screw 23 is fixedly installed on the output shaft of the third drive motor 22. A sliding sleeve 24 is threadedly connected to the second screw 23. A suction cup 25 is installed on the front side of the sliding sleeve 24.

[0025] After the product is formed and ejected by the demolding ejection component 10, the second drive motor 18 starts, driving the first screw 19 to rotate. The sliding frame 20 moves horizontally along the cross frame 17, moving the vertical frame 21 to the appropriate position. At this time, the third drive motor 22 starts, driving the second screw 23 to rotate. The sliding sleeve 24 moves up and down along the second screw 23, thereby driving the suction cup 25 to move up and down. Through the coordinated operation of the second drive motor 18 and the third drive motor 22, the suction cup 25 is accurately positioned in the horizontal and vertical directions, so that the suction cup 25 can accurately reach above the formed product. Then the suction cup 25 descends and adsorbs the formed product.

[0026] A placement rack 26 is provided at the right end of the unloading rack 16.

[0027] The surface of the placement rack 26 is equipped with anti-slip rubber pads, which can prevent the molded products from slipping and avoid scratches on the product surface due to collision.

[0028] A high-frequency vibrating screen is installed at the upper end of the powder storage silo 4, and the inner wall surface of the powder storage silo 4 is coated with a polytetrafluoroethylene anti-stick coating.

[0029] The high-frequency vibrating screen can effectively filter out large particles and lumps in the powder, ensuring that the powder entering the quantitative feeding component has a uniform particle size and improving the quality of powder side pressing molding. The polytetrafluoroethylene anti-stick coating can prevent the powder from adhering to the inner wall of the powder storage silo 4, reducing powder waste, and also facilitating the cleaning and maintenance of the powder storage silo 4.

[0030] The surfaces of the rear forming mold 6, the front forming mold 8, and the second screw 23 are all coated with a titanium nitride wear-resistant and non-stick layer.

[0031] The titanium nitride wear-resistant and anti-sticking layer has extremely high hardness and wear resistance, which can effectively resist the wear of powder on the post-forming mold 6, the front-forming mold 8 and the second screw 23 during the molding process, extending the service life of the equipment. At the same time, its good anti-sticking performance can prevent powder from adhering to the surface of the post-forming mold 6, the front-forming mold 8 and the second screw 23, ensuring the surface quality of the molded product, reducing product surface defects and improving the product qualification rate.

[0032] Working principle: When the equipment starts running, the powder to be processed is first poured into the powder storage silo 4. The high-frequency vibrating screen in the powder storage silo 4 starts working to filter the powder, removing any large particles and lumps that may be present, so that the powder entering the subsequent process has a uniform particle size. The filtered powder enters the conveying pipe 13 through the discharge port 12. At this time, the first drive motor 11 starts, driving the quantitative feeding auger 14 to rotate. The spiral blades of the quantitative feeding auger 14 convey the powder evenly according to the set pitch and speed. The powder enters the feeding buffer pipe 15 from the conveying pipe 13. The spiral guiding structure inside the feeding buffer pipe 15 guides the powder to fall slowly in a spiral shape, spreading evenly above the fixed outer mold 3, achieving precise quantitative feeding and avoiding powder blockage or uneven feeding. After the powder feeding is completed, the lateral main pressure cylinder 5 and the opposing auxiliary pressure cylinder 7 begin to work together. The lateral main pressure cylinder 5 pushes the forming mold 6 forward, while the opposing auxiliary pressure cylinder 7 pushes the forming mold 8 to remain stable, ensuring that the forces at both ends of the cavity are balanced, and performing lateral extrusion molding of the powder in the fixed outer mold 3. The powder is subjected to uniform pressure in the horizontal direction to form a powder product of the required shape and size. During the molding process, the electric telescopic rod 9 can adjust the position of the demolding ejection component 10 as needed. After molding is completed, the electric telescopic rod 9 pushes the demolding ejection component 10 forward to eject the molded product from the fixed outer mold 3. At this time, the second drive motor 18 starts, driving the first screw 19 to rotate. The sliding frame 20 moves horizontally along the cross frame 17 to move the vertical frame 21 to the appropriate position. Then, the third drive motor 22 starts, driving the second screw 23 to rotate. The sliding sleeve 24 moves up and down along the second screw 23, thereby driving the suction cup 25 to move up and down. Through the coordinated cooperation of the second drive motor 18 and the third drive motor 22, the suction cup 25 is accurately positioned in the horizontal and vertical directions, so that the suction cup 25 accurately reaches above the molded product. Then, the suction cup 25 descends to adsorb the molded product. Finally, the suction cup 25 adsorbs the molded product and moves it to the placement rack 26 on the right end of the unloading rack 16, placing the product on the placement rack 26.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
